Page 9 of 14 2-line filters B84776 IEC inlet filters Cautions and warnings Please read all safety and warning notes carefully before installing the EMC filter and putting it into operation (see ). The same applies to the warning signs on the filter. Please ensure that the signs are not removed nor their legibility impaired by external influences. Death, serious bodily injury and substantial material damage to equipment may occur if the appropriate safety measures are not carried out or the warnings in the text are not observed. Using according to the terms The EMC filters may be used only for their intended application within the specified values in lowvoltage networks in compliance with the instructions given in the data sheets and the data book. The conditions at the place of application must comply with all specifications for the filter used. Warning It shall be ensured that only qualified persons (electricity specialists) are engaged on work such as planning, assembly, installation, operation, repair and maintenance. They must be provided with the corresponding documentation. Danger of electric shock. EMC filters contain components that store an electric charge. Dangerous voltages can continue to exist at the filter terminals for longer than five minutes even after the power has been switched off. The protective earth connections shall be the first to be made when the EMC filter is installed and the last to be disconnected. Depending on the magnitude of the leakage currents, the particular specifications for making the protective-earth connection must be observed. Impermissible overloading of the EMC filter or filter, such as with circuits able to cause resonances, impermissible voltages at higher frequencies etc. can lead to bodily injury and death as well as cause substantial material damages (e.g. destruction of the filter housing). EMC filters and filters must be protected in the application against impermissible exceeding of the rated currents by overcurrent protective circuitry. In case of leakage currents >3.5 mA you shall mount the PE conductor stationary with the required cross section before beginning of operation and save it against disconnecting. For leakage currents IL1) <10 mA the PE conductor must have a KU value2) of 4.5 A3); for leakage currents IL 10 mA the PE conductor must have a KU value of 6.4) Output chokes and output filters must be protected in the application against impermissible exceeding of the component temperature. The converter output frequency must be within the specified range to avoid resonances and uncontrolled warming of the output chokes and output filters. 1) IL = leakage current let-go 2) The KU value (symbol KU) is a classification parameter of safety-referred failure types designed to ensure protection against hazardous body currents and excessive heating. 3) A value of KU = 4.5 with respect to interruptions is attained with: a) a permanently connected protective earth circuit 2.5 mm2 connected via shroud connectors (IEC 603092) and b) a protective earth circuit. 4) KU = 6 with respect to interruptions is achieved for fixedconnection lines 10 mm2 where the type of connection and line layout correspond to the requirements for PEN conductors as specified in relevant standards.

Page 10 of 14 2-line filters B84776 IEC inlet filters The table below summarizes the safety instructions that must be observed without fail. A detailed description can be found in the relevant chapters of the databook. Topic Instructions Selecting a filter When selecting a filter, it is mandatory to observe the rated data of the equipment (such as its rated input current, rated voltage, harmonic content etc.) as well as the derating instructions in Chapters 9 and 10. Rated voltage When power distribution systems deviating from the Power distribution symmetric TN-S system it is to check the suitability of systems, the EMC filters and the allowed voltages including the 7 fault cases. Protection from residual voltages Discharge resistors Active parts must be discharged within 5 s to a voltage of less than 60 V (or 50 C). If this limit cannot be observed due to the operating mode, the hazardous point must be permanently marked in a clearly visible way. Filters which are not permanently connected (e.g. when the test voltage is applied to the filter at the incoming goods inspection) must be discharged after the voltage has been switched off. Installing and removing of EMC filters Installation Reference chapter (data book), paragraph Selection guide for converter filters Safety regulations, 6.1 Safety regulations, 6.2 When installing and removing our EMC filters, a Safety regulations, voltage-free state must be set up and secured with 6.4 observance of the five safety rules described in EN 50110-1. Use in IT systems The special features of the IT system ("first fault case" Power distribution and other fault cases) shall be observed. system (network types), 7.6 Safety notes on leakage currents The filter leakage currents specified in the data book are intended for user information only.The maximum leakage current of the entire electrical equipment or appliance has to be limited for safety reasons. Please obtain the applicable limits for your application from the relevant regulations, provisions and standards. Leakage current, 8.4 Leakage current, 8.6 Voltage derating If the permissible limits for the higher-frequency Voltage derating, voltages at the filter are exceeded, the filter may be 9.8 Hazards caused by overloading the filters damaged or destroyed. Current derating at elevated ambient temperatures Non-observance of the current derating may lead to Current derating, overheating and consequently represents a fire 10.1 hazard.

Some parts of this publication contain statements about the suitability of our products for certain areas of application. These statements are based on our knowledge of typical requirements that are often placed on our products in the areas of application concerned. We nevertheless expressly point out that such statements cannot be regarded as binding statements about the suitability of our products for a particular customer application. As a rule, EPCOS is either unfamiliar with individual customer applications or less familiar with them than the customers themselves. For these reasons, it is always ultimately incumbent on the customer to check and decide whether an EPCOS product with the properties described in the product specification is suitable for use in a particular customer application. 2. We also point out that in individual cases, a malfunction of electronic components or failure before the end of their usual service life cannot be completely ruled out in the current state of the art, even if they are operated as specified. In customer applications requiring a very high level of operational safety and especially in customer applications in which the malfunction or failure of an electronic component could endanger human life or health (e.g. in accident prevention or lifesaving systems), it must therefore be ensured by means of suitable design of the customer application or other action taken by the customer (e.g. installation of protective circuitry or redundancy) that no injury or damage is sustained by third parties in the event of malfunction or failure of an electronic component. 3. The warnings, cautions and product-specific notes must be observed. 4. In order to satisfy certain technical requirements, some of the products described in this publication may contain substances subject to restrictions in certain jurisdictions (e.g. because they are classed as hazardous). Useful information on this will be found in our Material Data Sheets on the Internet (www.epcos.com/material). Should you have any more detailed questions, please contact our sales offices. 5. We constantly strive to improve our products. Consequently, the products described in this publication may change from time to time. The same is true of the corresponding product specifications. Please check therefore to what extent product descriptions and specifications contained in this publication are still applicable before or when you place an order. We also reserve the right to discontinue production and delivery of products. Consequently, we cannot guarantee that all products named in this publication will always be available. The aforementioned does not apply in the case of individual agreements deviating from the foregoing for customer-specific products. 6. Unless otherwise agreed in individual contracts, all orders are subject to the current version of the "General Terms of Delivery for Products and Services in the Electrical Industry" published by the German Electrical and Electronics Industry Association (ZVEI). 7.
